Configuration		Refers to the way a computer is setup; the combined hardware
		components (computer, monitor, keyboard, and peripheral devices) that
		make up a computer system; or the software settings that allow the
		hardware components to communicate with each other.
CPU		Central Processing Unit. The “brain” of the computer that performs the
		actual computations. The term Microprocessor Unit (MPU) is also used.
Crosspoint-		Highest performance FC fabric, providing a choice of multiple path
Switched		routings between pairs of F_Ports.
Topology
(FC-XS)
DMA		Direct Memory Access. A method of moving data from a storage device
		directly to RAM, without using the CPU’s resources.
DMA Bus		A feature that allows a peripheral to control the flow of data to and from
Master		system memory by blocks, as opposed to PIO (Programmed I/O) where
		the processor is in control and the flow is by byte.
Device Driver		A program that allows a microprocessor (through the operating system)
		to direct the operation of a peripheral device.
pc
EEPROM		Electronically Erasable Programmable Read Only Memory. A memory
		chip typically used to store configuration information.
EISA		Extended Industry Standard Architecture. An extension of the 16-bit ISA
		bus standard. It allows devices to perform 32-bit data transfers.
Exchange		A term that refers to one of the FC “building blocks”, composed of one
		or more nonconcurrent sequences for a single operation.
Fabric		FC defined interconnection methodology that handles routing in FC
		networks.
FC-EP		The future FC Enhanced Physical standard, which will build on and is
		compatible with FC-PH.
FC-PH		FC Physical standard, consisting of the three lower levels;
		FC-0, FC-1, and FC-2.
FC-0		Lowest level of the FC Physical standard, covering the physical
		characteristics of the interface and media.
